Interactions in Ecological Systems: Symbiotic Relationships and Nutrient Dynamics
Explore the intricate web of interactions within ecological systems, from diatom responses to nutrient availability affecting other organisms and the environment, to symbiotic associations between fungi and plants/algae leading to emergent properties in biological communities. Discover how mutualistic interactions in the soil improve plant nutrition and delve into the role of hormones in animals' responses to environmental changes.

Presentation Transcript
Day 7 AP Biology Review Ecology Interdependence with nature Lab #12 Dissolved Oxygen & Aquatic Primary Productivity
Ecological interactions Organisms interact with each other and the physical environment. In a short essay (100 150 words), explain how the response of diatom populations to a drop in nutrient availability can affect both other organisms and aspects of the physical environment (such as carbon dioxide concentrations).
Fungi have long formed symbiotic association with plants and with algae. In a short essay (100 150 words), describe how these two types of associations may lead to emergent properties in biological communities.
The soil in which plants grow teems with organisms from every taxonomic kingdom. In a short essay (100 150 words), discuss examples of how the mutualistic interactions of plants with bacteria, fungi, and animal improve plant nutrition.
In a short essay (100 150 words), use specific examples to discuss the role of hormones in an animal s responses to changes in its environment.
Lab #12 Dissolved Oxygen & Aquatic Primary Productivity O2 productivity Carbon fixation -(Growth) Consumption of CO2 These three quantities can be used to measure the primary productivity of a photosynthetic organism.
Discuss interactions of Biotic & abiotic factors and the carrying capacity of Earth, Who controls the food? Review Science, technology & society again. Philosophical Chair Debate Socratic Seminar Discussion
